SLIDING-JAW WRENCH.

Specification of Letters Patent.

Application filed March 20, 1906. Serial No. 307,113.

Patented July 24, 1906.

To a/ZZ whom it may concern,.-

Be it known vthat I, ARTHUR D. DAvrs, a citizen of the VUnited States, residing at Baggs, county of Carbon, and State of Wyoming, have invented certain new and useful Improvements in Sliding-J aw Wrenches, of which the following is a specification.

My invention relates to sliding-jaw wrenches having a locking-bar pivoted to the sliding jaw.

The object of the resent invention is the provision of a quie -acting wrench of the general class set forth wherein a novel frame construction is provided which insures proper guidance of the sliding jaw and prevents it from twisting and also renders the wrench of great strength and durability and cheapness of manufacture.

Another object of the invention is to provide a locking rack-bar pivoted to the sliding jaw and cooperating with the handle-frame in an improved fashion to lock the sliding jaw in adjusted position, permit rapid and easy adjustment and instantaneous locking of the sliding jaw.

Other objects of the invention will appear from the following description, wherein the construction is fully set forth, and the novel features are recited in the appended claims.

In the accompanying drawings, Figure 1 is a side view, Fig. 2 an edge view, and Fig. 3 a longitudinal section.

The frame 1 is made of a single piece of bar metal bent at 2 and having the legs or frame pieces thereof parallel and formed into guides 3, which are preferably cylindrical, these guides passing through the fixed jaw 4 and rigidly connected thereto by upsetting at 5. The sliding jaw 6 has openings 7, through which the guides 3 pass. A brace and locking-piece 8 connects the frame-pieces and is riveted thereto, this locking-piece having an opening 9 provided with a locking-tooth or shoulder 10.

The numeral 11 designates a locking-bar having teeth 1-2 and provided-at its free end with finger-holds 13, which project beyond opposite sides of the frame 1, so as to be in position to be grasped by the thumb and forenger. The locking-bar is entered loosely in the opening 14 in the sliding jaw and pivoted on a pin 15, and said locking-bar passes freely through the opening 9, and the teeth l2 are adapted to engage with the locking-shoulder 10, the bar being urged by a leaf-spring 16, Whichis secured to one of the pieces of frame 1 A wooden handle-piece 17, having grooved sides 18, which fit the flat side pieces of they frame 1, is fitted in between said framepieces and held by the screws 19 and 20. This handle-piece may be split longitudinally for convenience of insertion, if desired, in which case the two halves would be connected by a rivet or screw.

To adjust the sliding jaw, the user grasps the finger-holds 13 with thumb and foreiinger and draws back the locking-bar against the action of the spring, thereby disengaging the teeth 12 from the locking tooth or shoulder 10, whereupon the .sliding jaw can be moved to the desired position with the thumb and foreflnger, and upon release of the fingerholds the spring snaps the locking-bar into engagement with the tooth 10, thereby securely holding the sliding jaw in the desired position.

Having thus described my invention, what I claim as new, and desire t0 secure by Letters Patent, is"

1. A wrench comprising a frame or handlepiece having substantially parallel parts, a fixed jaw secured to said parts, a movable jaw mounted to slide on said frame parts, a cross-piece connected to and interposed between the frame parts and having an opening therethrough and provided with a lockingtooth, a toothed locking-bar pivoted to the locking-j aw and disposed between the frame parts and passing through the opening in the cross-piece and adaptedlto engage with the locking-tooth.
